VRV IV water cooled series

VRV IV W+ series - RWEYQ-T9

Ideal for high rise buildings, using water as heat source

Product Features

  • Environmental conscious solution: reduced CO2 emmisions thanks to the use of geothermal energy as a renewable energy source and typical lower refrigerant levels making it ideal to comply with EN378
  • Covers all thermal needs of a building via a single point of contact: accurate temperature control, ventilation, air handling units, Biddle air curtains and hot water
  • Unique zero heat dissipation principle obviates the need for ventilation or cooling in the technical room, maximising installation flexiblity
  • Incorporates VRV IV standards & technologies: Variable Refrigerant Temperature, VRV configurator, 7-segment display and full inverter compressors
  • Developed for easy installation and servicing: choice between top or front connection for refrigerant piping and rotating switch box for easy access to serviceable parts
  • Wide range of indoor units: possibility to combine VRV with stylish indoor units (Daikin Emura, Perfera)
  • Customize your VRV for best seasonal efficiency & comfort with the weather dependant Variable Refrigerant Temperature function. Increased seasonal efficiency and no more cold draft by supply of high outblow temperatures
  • Compact & lightweight design can be stacked for maximum space saving: 42HP can be installed in less than 0,5m² floorspace
  • 2-stage heat recovery: first stage between indoor units, second stage between outdoor units thanks to the storage of energy in the water circuit
  • Unified model for heat pump and heat recovery version and geothermal and standard operation
  • Variable Water Flow control option increases flexibility and control
  • 2 analogue input signals allowing external control of ON-OFF, operation mode, error signal, …
  • Easy compliance with F-gas regulation thanks to automated refrigerant containment check
  • The ability to control each conditioned zone individually keeps VRV system running costs to an absolute minimum
  • Spread your installation cost by phased installation
  • Keep your system in top condition via the Daikin Cloud Service: 24/7 monitoring for maximum efficiency, extented lifetime and immediate service support thanks to failure prediction


  • Inverter


    Inverter compressors continuously adjust compressor speed to actual demand. Fewer power-consuming starts and stops result in decreased energy consumption (up to 30%) and more stable temperatures.

  • Variable refrigerant temperature

    Variable refrigerant temperature

    The intelligent systems ensures highest energy savings with additional comfort to better suit application requirements.
